Thanks to sci-fi-rocks for following my story.

NicoleR85: thanks!

"And that weird munchkin lady with the big eyes? Do you remember? The way she looked at you! And then she opens her mouth and fire comes out!" the Doctor said enthusiastically.

"I thought I was going to get frazzled!" Rose said laughing.

"Yeah. One minute she's standing there, and the next minute roar!" the Doctor said mimic fire breathing out of his mouth, Rose copying him.

"Whatcha guys talking about?" Imogen asked walking in.

"We were just telling Mickey about the fire breathing munchkin lady", Rose replied. Imogen laughed remembering.

"That was a pretty close call for you. Good thing I was there to pull you out of the way in time Rose", she said. Imogen then noticed Mickey standing at the console holding a button down "what are you doing that for?"

"The Doctor told me to, half an hour ago", Mickey replied.

"You've been standing there for half an hour holding that button down?" Imogen asked and Mickey nodded.

"Er, you can let go now", the Doctor said and Mickey did so.

"Well, how long's it been since I could've stopped?" he asked the Time Lord.

"10 minutes", the Doctor replied. When Imogen gave him a look he confessed that it had been 29 minutes since he could've let go of the button.

"So you just forgot him?" she asked folding her arms.

"No, no, no!" the Doctor said quickly "I was just… I was just… I was calibrating" Imogen raised an eyebrow, clearly not believing him "I was just… No, I know exactly what I'm doing".

Imogen opened her mouth to retort when all of a sudden the console exploded. She and Mickey were thrown backwards by the force. The Doctor scrambles to his knees to try and operate the console as he and Rose were knocked off the captain's chair by the blast.

"What's happened?!" Rose shouted as she clung onto the console also on her knees.

"The time vortex is gone!" the Doctor yelled back "That's impossible. It's just gone!" Imogen tightened her grip on the console as the shaking grew more violent. "Brace yourself! We're going to crash!"

The four of them were thrown backward when the TARDIS came to a sudden stop, gasmasks dropping down from the ceiling. Imogen slowly sat up staring at the smoking console in the now darkened room. "Everyone all right?" the Doctor asked.

"I'm fine", Mickey replied.

"Me too", Rose added.

"Same here", Imogen put in. They all get to their feet.

"She's dead", the Doctor said quietly looking at the rotor and console "The TARDIS is dead".

"You can fix it?" Rose asked hopefully following the Doctor as he walked slowly around the console.

"There's nothing to fix. She's perished", the Doctor said. He pulled a lever back and forth fruitlessly "The last Tardis in the universe… extinct".

"So what do we do now?" Imogen asked wondering what they were going to do now the TARDIS wasn't working anymore.

"We could get help", Rose suggested.

"Where from?" the Doctor asked.

"Well, we've landed. We've got to be somewhere", Rose said.

"We fell out of the vortex, through the void, into nothingness", the Doctor told her "We're in some sort of no place…the silent realm…the lost dimension…"

"Otherwise known as London!" Mickey said from the door before stepping out. The Doctor, Rose and Imogen crossed the console room and out the door. "London, England, Earth. Hold on…" Mickey jumped off the low wall and picks up a newspaper from a dustbin and looks at the cover "First of February this year, not exactly far flung, is it?"

Rose jumped down and looked at the newspaper over his shoulder. Imogen jumped down from the wall to also look at the paper, completely missing the Doctor looking up at the sky. "So, this is London", he remarked jumping down from the wall.

"Yep", Mickey said popping the p.

"Your city", the Doctor continued.

"That's the one", Mickey confirmed.

"Just as we left it"

"Bang on", Mickey said.

"And that includes the zeppelins?" the Doctor asked. Mickey, Rose and Imogen look up at him, then follow his gaze to see the sky full of zeppelins.

"What the hell…?" Mickey breathed, gaping up at them.

"That's beautiful", Rose commented.

I've seen better the Doctor thought looking at Imogen who was staring up at zeppelins. "Same place, same date but slightly different. It's a parallel world isn't it?" she asked.

"Must be", the Doctor agreed. It was the only thing that made sense.

"So, a parallel world where…" Rose began.

"Oh, come on. You've seen it on films. Like an alternative to our world where everything's the same but a little bit different", Mickey said understanding where Imogen got the idea of a parallel Earth "like, I don't know, traffic lights are blue, Tony Blair never got elected…"

"And he's still alive…" Rose said distant, staring at a poster. It featured her father holding a bottle in his hand. Vitex according to the advert. "A parallel world and my dad's still alive", she said walking towards it. The Doctor, Imogen and Mickey follow her.

Immediately the Doctor's mind had gone back to the last time they'd met Rose's father. She'd wanted to be there for him, to hold his hand while he died but instead she saved his life. That caused the Reapers to appear. To make matters worse, Rose caused a paradox by touching her younger self allowing the creatures inside the church they were holed up in. Imogen had saved his life that day at the expense of her own. The Doctor probably would've taken Rose home after that trip if it wasn't for the fact that Imogen didn't seem to remember being taken by the Reaper. Or so she claimed.

Still it made the Doctor a little uneasy to have Imogen in a place where Pete Tyler was still alive. "Don't look at it, Rose", the Doctor said sternly "Don't even think about it. This is not your world".

"But he's my dad…and…" Rose reached out and touched the poster. She stepped back as the poster came to life.

"Trust me on this", Pete said giving a wink and a thumbs up.

"Well, that's weird. But he's real!"

"Trust me on this" Pete repeated.

"He's a success. He was always planning these daft little schemes. Health food, drinks and stuff. Everyone said they were useless. But he did it", Rose said happily.

"Rose, if you've ever trusted me, then listen to me now", the Doctor said after he'd taken hold of Rose by her shoulders and turned her to face him. Rose glanced back at the poster "Stop looking at it!" Rose reluctantly meets the Doctor's eyes again "Your father's dead. He died when you were six months old. That is not your Pete. That is a Pete. For all we know, he's got his own Jackie, his own Rose. His own daughter who is someone else, but not you" Rose's eyes started to wander back to the poster but she tries to stop herself "You can't see him. Not ever".

The blonde gives the Doctor a small nod to tell him that she understood what he was saying.

~...~

Imogen wandered around the console flicking the odd switch here and there to see if she could get any kind of response. "Come on old girl give me something", she murmured. It was no big surprise that she didn't get any response from the TARDIS. Imogen glanced at her jacket pocket when she heard a noise, it was her phone. She pulled it out and saw that her mobile had connected to something called Cybus Network.

When the Doctor entered the TARDIS, Imogen was sitting on the captain's chair looking at her phone. "You ok?"

"Yeah", she replied sounding a little distracted as she stared at the screen of her mobile.

"What is it?" the Doctor asked sitting next to her.

"My phone connected to this thing called Cybus Network, it allows me to access the internet", Imogen said.

"Whatever it says this is the wrong world", the Doctor warned.

"I know it's the wrong world Doctor. For starters Aunt Ellie is alive", Imogen said, still looking at the screen.

"Gen…" the Doctor started

"Don't tell me that I can't see her. I know I can't", Imogen said interrupting him "I'm just happy that my cousin has her mother in this world. Also if we're stuck here for a bit at least I know there's no risk of running into myself".

"Why?" the Doctor asked.

"According to the Cybus Network I don't exist", Imogen said looking up at him "My parents still got married and divorced a few years later, so that's the same. But there's no record of me. I guess they never had kids. And before you say anything I'm not going to ask to see Sarah Jane because she isn't my mother. I have my own Sarah Jane in our world".

The Doctor thought she was being remarkably sensible about the whole thing considering that her aunt was alive in this parallel world. They looked over at the TARDIS doors they heard them open "I told you to keep an eye on her", the Doctor said seeing Mickey enter.

"She's all right…" Mickey said rather dismissively.

"Mickey she's far from alright. Her father is alive in this world and that has to be pretty tempting for her", Imogen said.

"Imogen's right. She can't go wandering off. Parallel world, it's like a gingerbread house. All those temptations calling out", the Doctor said standing up.

"Well what about me? Nothing out there to tempt me?" Mickey asked.

Imogen opened her mouth to say something when the Doctor spoke first "Well, I don't know, I can't worry about everything…if I could just get this thing to…" the Time Lord kicked the console hard in frustration.

"Did that help?" Mickey asked.

"Yes", the Doctor replied.

"Did that hurt?" Imogen asked as he sat down on next to her.

"Yes", the Doctor repeated rubbing his converse clad foot.

Imogen shook her head "you should never use force Doctor. You'll just embarrass yourself", she said.

"Thanks for that wonderful piece of advice", the Doctor said sarcastically still rubbing his foot.

"You're welcome"

The Doctor stopped rubbing his foot and considered the dark console. "We're not meant to be here. The Tardis draws it's power from the universe, but it's the wrong universe", he said to Mickey and Imogen.

"Think of it like diesel in a petrol engine", Imogen explained to Mickey.

"But I've seen it in comics. People go hopping from one alternative world to another. It's easy", the man said leaning against the console.

The Doctor gave him a withering look "Not in the real world" he paused "It used to be easy. When the Time Lords kept their eye on everything, you could hop between realities, home in time for tea. Then they died, and took it all with them. The walls of reality closed, the worlds were sealed. Everything became that bit less kind"

"If the walls between worlds were sealed, how did we get here?" Imogen asked.

"I don't know. Accident?" the Doctor answered sounding weary "Should've been impossible. Now we're trapped".

Imogen took his hand "we're not trapped, just inconveniently circumstanced", she said trying to make him feel better. The Doctor smiled knowing what she was trying to do.

"Any feelings or instincts?" the Time Lord asked.

"No I…" Imogen trailed off when she spotted a tiny green glowing light underneath the console "what's that?" she asked pointing.

"What?" Mikey asked trying to see what she was pointing at.

"Is that a reflection?" the Doctor asked getting up to have a closer look "It's a light! Is it? Is that a light?"

"Yeah I think it is", Imogen confirmed when she got up to take a look. The Doctor and Mickey pull off the grilling to reveal a small green light.

"We've got power! Gen, Mickey, we've got power! Ha!" the Time Lord said excitedly. He jumped down and started pulling out some important looking internals. "It's alive!" the Doctor said deliriously happy when he reached the light.

"What is it?" Imogen asked kneeling down on the grill.

"It's nothing. It's tiny. One of those insignificant little power cells that no one ever bothers about, and it's clinging onto life, with one little ounce of reality tucked away inside", the Doctor explained.

"Enough to get us home?" Mickey asked hopefully.

"Not yet" the Doctor picked up the power cell and sat back on the small set of stairs under the grilling "I need to charge it up".

"We could go outside and latch it up to the National Grid", Mickey suggested.

"Wrong sort of energy. It's got to come from our universe", the Doctor said holding the power cell carefully in both hands.

"But we don't have anything", Mickey pointed out.

"Yes we do", Imogen said taking the power cell from the Doctor. Carefully cupping in her hands, she gently blew on it. The Time Lord's eyes widened as the green light grew brighter. He looked at Imogen slightly at a loss for words.

"You…how…?" the Doctor just couldn't seem to form a proper sentence he was that amazed. She'd just powered up a power cell, a Gallifreyan power cell by breathing on it.

"It's going out", Mickey said watching the light fade "is that ok?" he asked worried.

"Yes. It's on a recharging cycle It'll loop round, power back up and be ready to take us home in…" Imogen tilted her head thinking about it "I'd say about 12 hours".

"So that gives us 12 hours on a parallel world?" Mickey asked Imogen as the Doctor was still finding it hard to talk.

"Yep", Imogen answered.

"Gen…you're incredible", the Doctor breathed finally being able to form an actual sentence. He cupped her face and dropped kiss on the top of her head "You beautiful, amazing, impossible girl", he said causing Imogen to blush which of course made him smile. He kept both hands on her cheeks as he gazed into her violet eyes. Imogen didn't move nor did she remove his hands from her face as she too had become rather lost in his brown eyes. The pair was startled when Mickey spoke.

"Uh guys?" The Doctor took his hands away from Imogen's face and they looked at the man "we should probably tell Rose the good news", Mickey said.

"Yeah that's a good idea", Imogen agreed standing up.

"Yeah good idea", the Doctor mumbled under his breath as he followed Imogen and Mickey out of the TARDIS.

The trio found Rose sitting on a bench. "There you are! You all right? No applause, I fixed it", the Doctor said taking the power cell from Imogen and showing it to Rose.

"Actually Imogen fixed it", Mikey pointed out putting an arm around the girl's shoulders.

"Thank you Mickey", Imogen said.

"Yes thank you Mickey", the Doctor repeated giving the man a look. Mickey knew what that look meant and removed his arm from around Imogen's shoulders. If that little moment in the TARDIS was anything to go by, Mickey was sure that the Doctor had feelings for the girl.

"In 12 hours we'll be heading back to our reality", Imogen said sitting down next to her friend, not having noticed the look the Doctor gave Mickey. That was when she noticed Rose was staring at her phone. "What is it?" she asked.

"My phone connected. There's this Cybus Network", Rose said.

"Yeah my phone connected to it too", Imogen told her.

"Rose, whatever it says, this is the wrong world", the Doctor reminded her.

"I don't exist", the blonde continued.

"Welcome to the club. I don't exist in this place either", Imogen told her "I checked".

"What about your aunt?" Rose asked wondering if it was the same case for Imogen as it was for her. Dead in their world but alive in this parallel one.

"She's alive", Imogen replied happily "how about your parents? They together?"

"Yep. They're rich. They've got a house and cars, and everything they want" Rose paused thinking "But they haven't got me" she got up from the bench and walked away. Then she turns to face the Doctor, Mickey and Imogen "I've got to see him", she said.

"You can't", the Doctor insisted.

"I just want to see him", Rose argued.

"I can't let you", the Doctor said. He should've seen this coming. Rose wasn't going to be a sensible as Imogen about the situation, of course she was going to want to see her father.

"Imogen just said 12 hours!" Rose retorted.

"You can't become their daughter, that's not the way it works", the Doctor firmly.

"He's right Rose. You can't just become their daughter. What about your actual mother in our world? She only has you and if you leave her, she'll have no one", Imogen put in.

"I just want to see my dad Imogen", Rose repeated stubbornly. Imogen sighed and turned to Mickey for help. But it seemed he had other ideas.

"12 hours, yeah?" he asked thoughtfully as he started to back away. If Rose's father and Imogen's aunt were alive in this world it's possible that his gran was too. He had to find out.

"Where're you going?" the Doctor asked bewildered.

"Well, I can do what I want", Mickey replied.

"I've got the address and everything", Rose added starting to back away too. The Doctor stood there with Imogen looking from one to the other as they backed away. "Stay where you are, both of you! Rose, come back here! Mickey, come back here right now!"

"I just want to see him", Rose repeated.

"Yeah, I've got things to see and all", Mickey added.

"Like what?" the Doctor asked.

"Well, you don't know anything about me, do ya?" Mickey countered angrily "It's always about Rose and Imogen. I'm just a spare part"

"I'm sorry. I've got to go", Rose said still walking backward. The Doctor looks between them torn as to who he should go after.

"Go on, then. There's no choice, is there?" Mickey asked gesturing at Rose "You can only chase after one of us. It's never going to be me, is it?" Rose stops walking backward, turns and leaves. Mickey also turns around knowing that the Doctor would never go after him.

"Go with Rose. I'll go with Mickey", Imogen said deciding to make the choice for the Doctor.

"Meet back here in 12 hours", the Doctor told her and she nodded. Imogen turned to run after Mickey when the Doctor stopped her "be careful".

"I will", she promised.
